EXHAUST EMISSION CONTROL SYSTEM

摘要

An exhaust emission control system [1] comprising a continuous regenerating DPF [13] and a DPF controlling means [30C], wherein control is so performed as to accept the operation of a forced regenerating means [34C] at an operation request by a driver when it is judged a traveling distance [”Mc] after starting collection detected by a traveling distance detecting means [33C] has reached a specified judging traveling distance [”M1] even when the DPF controlling means [30C] detects a collection amount [”Pm] detected by a collection amount detecting means [32C] is smaller than a specified judging collection amount [”P1]. Accordingly, in a continuous regenerating DPF [13] capable of manual regenerating, the number of warning such as a blinking regeneration button prompting a manual regeneration is reduced to relieve a driver of trouble.
